Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The batch-start flow now loads all active intents, but duplicate cleanup can still cancel a valid intent after another conflicting intent is removed, potentially dropping work. This bounded correctness issue should be fixed or explicitly accepted before merge. Possibly related issues

- Around line 309-314: Replace the per-VTXO latest-intent logic in the
intentsToCancel calculation with one global selection across all duplicate
claims: sort intents by descending updatedAt with a stable txId tie-breaker,
retain an intent only when none of its claimed VTXOs conflict with already
retained intents, and cancel every remaining intent. Use the existing
duplicateVtxos and intent claim data, ensuring an intent claiming multiple VTXOs
is evaluated atomically.

Resolve duplicate claims as one global selection.
This code cancels losers independently for each VTXO. An intent can claim multiple VTXOs. For example, if A claims x,y, B claims x, and C claims y, then A can lose to C while B is also canceled because it lost to A. The result retains C and incorrectly removes the now non-conflicting B.
Sort intents by a deterministic priority, retain an intent only when none of its VTXOs conflict with already retained intents, and cancel only the remaining intents. Include a stable tie-breaker when updatedAt values are equal.

check again, duplicateVtxos is a map of a vtxo to all intents claiming it, so we need to find the latest intent among them

@shubertm, duplicateVtxos has the required claim information. The issue is the independent selection for each map entry.
For A -> {x, y}, B -> {x}, and C -> {y}:
- If
Ais latest forx, the code cancelsB. - If
Cis latest fory, the code cancelsA. Bthen remains non-conflicting, but the code has already canceled it.
The selection must evaluate each intent and all of its VTXOs as one unit. The finding remains valid.
